NOVELTY - High temperature resistant flame-retardant nylon graphene composite material comprises 95-105 pts. wt. nylon salt, 2-10 pts. wt. graphene oxide, 4-8 pts. wt. brucite fiber, 3-8 pts. wt. expanded graphite, 2-6 pts. wt. silane coupling agent KH560 (3-glycidoxypropyltrimethoxysilane), 1-4 pts. wt. nano-carbon sol having solid content of 20-25%, 1-4 pts. wt. nano titanium dioxide, 2-5 pts. wt. talc powder, 0.2-1 pts. wt. blocking agent, 0.1-0.6 pts. wt. 6-aminocaproic acid and 40-70 pts. wt. deionized water. USE - Used as high temperature resistant flame-retardant nylon graphene composite material. ADVANTAGE - The nylon graphene composite material has mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing nylon graphene composite material, comprising (i) mixing uniformly nylon salt, graphene oxide, blocking agent and 6-aminocaproic acid, and ultrasonic dispersing at 50-85 degrees C for 1-3 hours to obtain a premix, and adding the premix into high-pressure reaction kettle, (ii) adding nano-carbon sol having solid content of 20-25%, brucite fiber, expandable graphite, silane coupling agent KH560 (3-glycidoxypropyltrimethoxysilane), nano titanium dioxide and talc powder into deionized water, mixing uniformly under ultrasonic agitation condition, then adding into the high pressure reaction kettle, and (iii) replacing air in the high pressure reaction kettle with nitrogen gas for at least three times, under nitrogen gas atmosphere, heating to 160-260 degrees C and pressurizing to 2-3.5 MPa, releasing water vapor in the reaction kettle at 2-3.5 MPa, carrying out pressure reaction for 1-3 hours, releasing pressure in the reactor to atmospheric pressure, then discharging, and reacting at not greater than 280 degrees C.
